SANITARY CISTERN.

Specification of Letters Patent.

Application filed July 6, 1915. Serial No. 38,152.

To all whom it may concern:

'Be it known that I, JAMES H. KELLER, a citizen of the United States, and a resident of Fort Myers, in the county of Lee and State of Florida, have invented certain new and useful Improvements in Sanitary Cisterns, of which the following is a specification, reference being had to the accompanying drawings.

his invention has relation to certain new and useful improvements in receptacles for storing water, and comprises a sanitary cistern including a peculiarly constructed supporting frame, the construction being such that the cistern, which has a settling chamber, can be easily flushed to clean the same; and the object of my invention is to provide a device of this general character of a simple and inexpensive nature and of a. compact and durable construction, which shall be capable of convenient and accurate adjustment in position.

With these and other objects in view the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claims, it being further understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the accompanying drawings forming a part 0 this specification, and in which like numerals of reference indicate similar parts in the several views:

Figure 1 shows a side elevational view of a cistern embodying my invention.

Fig. 2 is a top view.

Fig. 3 is a central sectional view.

Fig. 4 shows a top view of the supporting frame.

Fig. 5 shows a perspective detail of one of the supporting standards.

In carrying out the aim of my invention I employ a cylindrical tank 1 provided with the preferably dished top 2 and the conical bottom 3. This bottom 3 ends in a flushing valve 4 having the operating stem 5, the lower part w of this conical bottom forming a settling chamber, as clearly shown in Fig. 3.

Secured within the bottom 3 a suitable distance above the flushing valve 4; is the drain cock 6, while located near the bottom of the tank 1 is the faucet 7, as clearly shown.

Near the top I provide the wire gauze strainer 8, into which empties the water inlet pipe 9 provided with the valve 11. Extending from the upper end of the tank 1 is the overflow pipe 10.

The tank is supported by means of a peculiarly constructed frame including a plurality of supporting standards preferably made of sheet steel, though the same may be made of any other suitable material.

As shown in Fig. 1, each standard comprises an outer section a, an inner section 2), and an upper or top section 0. This upper section 0 is provided with the outstanding flanges 12 and 13 bent in opposite directions, while at the bottom are the base or securing flanges 14E.

Arranged to engage the lower end of the tank 1 is the upper securing rim 15 having the outstanding flange 16. while arranged to engage the conical bottom 3 intermediate of its ends is the flared rim 17, this construction being clearly shown in Fig. 1.

Connecting these rims 15 and 17 and holding them in spaced relation are a plurality of connecting plates 19, four sets of such plates being used, as shown in the drawings. As disclosed in Fig. 1, each connecting plate 19 ends in an obliquely extending car 20, these cars being arranged to be secured to the cylindrical rim portion 15, and held against the underface of the outstanding flange 16, thus providing a firm and secure connection.

The upper and lower flanges 12 and 13 are securely fixed to these connecting plates 19. Connecting the standards at their lower ends are the cross-braces 22, as shown in Fig. l.

Located at a suitable faucet 7 is the shelf A, vessel to receive the tank is placed.

lVhile I prefer making the tank of sheet steel, it should be understood that the same may be made of wood, cement, or any other suitable material.

As shown in Figs. 1 and 3, the lower cylindrical end of the tank 1 is engaged by the cylindrical rim 15, the upper ears 20 being secured by means of suitable rivets U to the rim 15.

The tank is simple and inexpensive in construction, and both durable and eflicient in operation, and may be flushed and cleaned with ease, accuracy and despatch.

While I have described an extending car 20, this ear is not absolutely necessary as point below the upon which the water emptied from the the same may be eliminated, as shown in Fig. 5.

Having thus described my said invention, What I claim as new and desire to secure by Letters Patent is:

1. A sanitary cistern comprising a cylindrical tank having a bottom, of a rim sur rounding said tank near its lower end having an outstanding flange at its upper edge, and a plurality of standards each having upper oppositely directed securing edges arranged to be fixed to said tank bottom and an upstanding end ear secured to said rim and held against said outstanding flange, as and for the purpose set forth.

2. A sanitary cistern comprising a cylindrical tank having a bottom, of a supporting frame comprising an upper cylindrical rim having an outstanding flange at its upper edge, a lower flared rim of less diameter, a plurality of connecting plates to hold said rims in spaced relation, each connecting plate endingin an obliquely extending ear secured to said upper rim and held against sa1d outstanding flange, a plurality of supporting standards each having an upper and a lower securing flange said flanges being bent in opposite direction and secured to said connecting plates, said cylindrical rim surrounding said tank near its lower end, said flared rim engaging said bottom, and a plurality of cross-braces connecting said standards at their lower ends.

3. A sanitary cistern comprising a cylindrical tank having a bottom, a supporting frame comprising an upper cylindrical rim having an outstanding flange at its upper edge secured to a cylindrical part of said tank, a loWer flared rim secured to said conical bottom, and a plurality of supporting standards each having an upper and. a lower securing flange said flanges being bent in opposite directions and secured to said bottom and said rims.

In testimony whereof I aflix my signature, in the presence of two Witnesses.
